fundamentals_income_ statements
SEC-reported income statements (revenue through net income and EPS), quarterly, annual or TTM (default quarterly, last 8). Rows whose accounting does not add up, and every bank, insurer or IFRS filer's rows, are checked against the company's SEC filing. statement_check.status is sec_confirmed, sec_corrected (a line taken from the filing: field_basis names it, the prior figure is vendor_<field>) or sec_check_unavailable (lines withheld; retry shortly). A withheld line is null with its reason in fields_withheld; fields_unverified is {field: reason} for figures kept that the filing cannot confirm; a field_basis entry with served false holds the check_values a figure was compared with, not served. per_share_restated marks a restated EPS. Banks show net_interest_income, not gross profit. EPS is as filed; *_split_adjusted puts it on today's share basis. quarters_missing lists absent quarters. eps_repair logs an EPS fixed for contradicting its net income. An unknown symbol is refused 404 unknown_ticker (not billed).
Parameters
Query
tickerstringRequiredperiodstringOptionalannualquarterlyttmquarterlylimitintegerOptional81 to 200Response
A 200 is a JSON envelope: ok: true and this endpoint's own fields (see Fundamentals). It carries X-Request-ID, the credit headers (X-Credits-Cost, X-Credits-Remaining, X-Credits-Receipt, X-Credits-Settlement) and the rate-limit headers.
A 200 is billed even when it holds no data (an empty list, null, found: false), so check those fields. Pricing & credits explains the credit headers.
Errors
No error is billed. The body is { "ok": false, "error", "detail", "request_; read the code from error.
| Error | Meaning |
|---|---|
400 invalid_ticker | The request is malformed, for example a ticker that is not a symbol: invalid_ticker, refused before any credit is reserved, with param naming the parameter. Not billed. |
401 unauthorized | Missing or invalid API key. |
402 plan_required | Your plan does not include this tool, you are out of credits, or your workspace's spend cap paused its keys. plan_required names the plan that unlocks the tool; usage_exceeded means the credit balance is spent; spend_cap_reached means the key is paused until the cap resets or is raised: detail names the cap and the reset, cap_usd and resets_at (ISO 8601) carry them, and doc_url links pricing and credits. Not billed. |
403 scope_denied | This API key is limited to some products and this tool is not one of them. product names the tool's product and scopes the key's products. An upgrade does not change it: use a key whose scopes include the product, or change this key's scopes. Not billed. |
404 unknown_ticker | No data source lists this ticker, active or delisted: the market-data listing and the security master both say it does not exist. param names the parameter. Not billed. Best-effort: it is answered only when the route itself found nothing, and after 20 lookups of new symbols per API key per minute the route's own answer stands. |
422 validation | A parameter is missing, out of range or the wrong type; param names it. Not billed. |
429 rate_limited | Your plan's rate limit is spent for this window. Retry after Retry-After seconds. Not billed. |
503 paid_ | The data could not be served completely right now; retry later. Not billed. |
504 request_timeout | The request ran past the server's time budget; retry. Not billed. |
